I sleep sometimes in my life and today when I wake up, I have a huge vision. That would be a huge mistake to trade Zharovsky. Demidov try to mentor him, he will said to him that you need to work hard, Demidov is the best mentor possible, he isn't Nathan Beaulieu with Alex Galchenyuk, Demidov have winner mentality.
Hockey is a business, Hage story is beautiful, but if you want a great top 6 C, sacrifice Hage. If not, be patient and try to acquire something else, without trading Hage.
But trading Zharovsky over Hage, would be a huge mistake, that's my vision said to me.
